Using an in vitro model in which endothelial cells can be induced to invade a three-dimensional collagen gel to form capillary-like tubular structures, we demonstrate that leukemia inhibitory factor (LIF) inhibits angiogenesis in vitro. The inhibitory effect was observed on both bovine aortic endothelial (BAE) and bovine microvascular endothelial (BME) cell, and occurred irrespective of the ang...
Leukemia inhibitory factor (LIF) is a member of the interleukin-6 (IL-6) cytokine family. All members of this family activate signal transducer and activator of transcription 3 (STAT3), a transcription factor that influences stem and progenitor cell identity, proliferation and cytoprotection. The role of LIF in development was first identified when LIF was demonstrated to support the propagatio...
The objective of this study was to observe the expression of leukemia inhibitory factor (LIF) in animals and in different clinical grades of patient osteoarthritic tissues. Thirty-five rabbits were used in a Colombo model of experimental osteoarthritis (OA). Five rabbits each were sacrificed on postoperative days 3, 7, 14, 28, 42, 56, and 84. Immunohistochemistry analysis for LIF expression and...
introduction: to improve the development of embryo in vitro several attempts have been made, including the application of leukemia inhibitory factor (lif). this factor plays an important role in embryo development and has been shown to enhance in vitro development rate in sheep and mice. there is controversy regarding the effect of lif on the different stages of embryo development. the aim of t...
Leukemia inhibitory factor (LIF), a secreted cytokine, plays an important role in a wide array of biological processes including inducing differentiation of leukemia cell, inflammatory response, neuronal development, embryonic implantation, stem cell self-renewal and cancer progression, etc. LIF exerts its biological functions mainly through the activation and regulation of JAK/STAT3, AKT, EKR1...
Background: This study was performed to investigate the rate of inner cell mass of blastocyst which obtain from culture of mouse two cell embryos in presence and absence of recombinant of human leukemia inhibitory factor. Materials and Methods: ICR female mice that were between 6-8 weeks old received intra peritoneal injection of 7.5 IU of pregnant mare serum gonadotropine for super ovulati...
Abstract Background and objectives: Meningitis is one of the most common infectious of the central nervous system (CNS), defined as an inflammation of the meninges. LIF is a potent pro-inflammatory factor. Cerebrospinal fluid (CSF) contains the growth factors and cytokines whose concentrations have been changed in most neurological diseases. The aim of this study was to determine the LIF conce...
Receptors for murine leukemia inhibitory factor (LIF) were demonstrated on immature and mature murine megakaryocytes. LIF alone had no effects in culture on the survival or proliferation of normal murine megakaryocytes or their precursors. However, combination of LIF with multipotential-colony-stimulating factor (Multi-CSF) (interleukin-3) enhanced the megakaryocyte colony formation able to be ...
Background: Leukemia inhibitory factor (LIF) is a neurortophic cytokine which plays an important role in the neural cell survival. Expression of LIF and its receptor, LIFR, in different brain regions has been demonstrated. Based on evidences LIF plays an important role in the modulation of neurogenesis and glial responses to injury. Up-regulation of LIF after central nervous system (CNS) damage...
